Rock Island plow Company Catalog
This would date from 1924 to probably 1926 based on the inclusion of the Heider 15-27 but not the later modern Rock Island tractors. Thank you for uploading this and if there is anymore Rock Island Plow company books that can be uploaded it would be appreciated. And yes, the Dallas Texas branch office building pictured is the infamous Texas Book depository.
